Efecto de diferentes niveles de Plukenetia volubilis L. (Sacha inchi) en el engorde de Broilers.

Abstract

Sacha Inchi flour (Plukenetia Volubilis L.), was used in broiler chicken feed as soybean partial substitution alternative. The experiment was performed in La Bretania farm, in Pallatanga Cantón, Chimborazo Province. Sacha Inchi samples were taken from Macas and Puyo with an approximately weight of one kg. Four Sacha Inchi experimental diets were formulated at 0,5,10 and 15% addition. For each treatment 50 broiler chickens were used, which were distributed under a completely randomized design, the feed phase, was 49 days. Sacha Inchi flour adds: metabolizable energy of 3435,5 kcal/kg, determined by near infrared reflectance spectroscopy (NIRs); 42% crude protein (CP), 8.39% ash (C), 8.80% fiber (F), 6.24% fat. Performance parameters expresed in weight gain and dry matter intake are statistically higher (P<0.01) in broilers fed diets 10% of Sacha Inchi, with carcass yield of 2214.26 g and feed conversion 1.25. The physiological parameters evaluated as: liver, bursa, of Fabricius, spleen, guts, do not represent significant differences (p=0.05). Sacha Inchi flour inclusion determined the opportunity to take advantage of a 1.39 USD Benefit/Cost at 10% of the raw material, showing that it is possible to replace the traditional diets ingredients maintaining a good productive and physiological behavior in broiler chickens. It is recommended to test the inclusion of Sacha Inchi as food for other species such as guinea pigs, rabbits, pigs, horses and cattle. Key words: sacha inchi flour, broiler chickens.
